Hi Ruiyi, I think you are missing the initial conditions file (IC File, Row 3 on Basic parameters tab). You should input here the exported results from your rigid simulation. You can see how to export your rigid simulation results here http://simvascular.github.io/docsFlowSolver.html (Simulation Gui...

Hello Ruiyi, what are your initial conditions for the deformable wall simulation? You should be using your rigid wall simulation results as initial conditions for the deformable wall simulation. Starting form zero initial conditions may result in divergence of your simulation. You can find the detai...
